COMBINED RAILROAD-RAIL AND CHAIR AND METHOD OF MAKING THE SAME.

SPECIFICATION forming part of Letters Patent No. 482,805, datedSeptember 20, 1892.

Application filed February 2, 1892. Serial No. 420,092. (No model.)

To aZl whom it may concern.-

Be it known that I, ARTHUR J. ll/IOXHAM, of Johnstown, in the county ofCambria and State of Pennsylvania, have invented a new and usefulCombined Railroad-Rail and Chair and Method of Making the Same, whichinvention is fully set forth and illustrated in the followingspecification and accompanying drawings.

The object of this invention is to weld a rail and chair together insuch a manner that weakness and tendency to fracture at the junction ofthe parts will be avoided.

The invention will first be described in detail, and then particularlyset forth in the claims.

In the accompanying drawings, Figure 1 shows in cross-section a rail andchair embodying my invention. Fig. 2 is a side ele- Vation of Fig. 1

In the figures the several parts are respect ively indicated byreference-letters, as follows:

The letter A indicates the web of the rail, provided with a bead or bulba, and B the web of the chair or support,which is also provided with abead or bulb b. The two beads a, and b are usually of about the samediameter and shape, approximately cylindrical, and the union betweenrail and chair is effected by welding said beads together. This weldingmay be accomplished by any suitable process or means.

In the welding of chairs to rails if a sharp angle be left at thejunction of rail and chair, as has heretofore been the practice, suchangle is a source of weakness in the union of the parts and causesfracture at this point. To avoid these undesirable results, I supply anexcess of material in the upper part of the chair,which is heated duringthe Welding process, so that when the parts are subjected to thepressure needed to properly bring the rail and chair together to eifecttheir welding such excess of metal is pressed out endwise, and thusproduces a fillet in the two angles at the junction of the rail andchair, such junction at the ends of the chair being on curved or concavelines, as shown at c c, Fig. 2. The desired excess of material can beregulated, if desired, by the insertion of a filling piece or pieces ofany suitable thickness between the rail and chair. Such piece or piecesbecoming welded into and part of the rail and chair, the excess of metalwill produce the fillets shaped substantially as shown atthe points a c,Fig. 2.

I do not limit myself to any particular manner of constructing orproducing the fillets c c, for whether they are separately welded on orproduced in any other manner it is evident that they serve the samepurpose and they are within the purpose and principle of my invention.

Having thus fully described my said invention, I claim- 1. As a newarticle of manufacture, a railway-rail and chair or support Weldedtogether, the junction of the rail and chair at the ends of the latterbeing made on curved lines.

2. As a new article of manufacture, a railway-rail and chair or supportWelded together, the ends of the chair at its junction with the railhaving imparted thereto a concave form.

3. As a new article of manufacture, a railway-rail and chair or supportWelded together, said chair being enlarged in dimension at the points 0c of its junction with the rail.

4:. The method herein described of welding railroad-rails and chairstogether, consisting in first forming a rail and chair each with a beador bulb on avertical web and then pressing out the metal of the chair atits ends into fillets or curves, thereby lengthening the chair at theWeld, substantially as and for the purposes set forth.
